사회는 매우 빨리 변화하고 있으나 변화의 핵심 인력과 기술을 제공해야하는 이공계대학의 교육과정은 이러한 변화의 속도를 따라가지 못하고 있다. 사회에서는 한 명이 수만 명을 먹여 살릴 수 있는 소위 gold color engineer 를 요구하고 있으나 대학의 반응은 아직까지 미진하다. 따라서 이런 사회의 빠른 변화에 대응하여 이공계교육이 적절히 변화할 수 있는 교육시스템의 구축이 매우 필요하다. 본 논문에서는 이를 위하여 이공계 대학교육과정의 문제점을 분석하고 그 개선방안을 논하고자 한다. 이공계 교육 내용에 대한 공급자와 수요자의 차이를 분석하고 이를 제고하기 위하여 새로운 교육체계를 제시하였다. 직업기초능력에 대한 설문을 실시하였고 국내외 이공계 교육 현황과 최근 국내 이공계 신입생의 과목이수 내용 등을 조사하였다. 또한 교육과정 개선을 위한 국가의 지원 방안을 제시하였다.

In this study, we synthesize tungsten oxide thin films by electrodeposition and characterize their electrochromic properties. Depending on the deposition modes, compact and porous tungsten oxide films are fabricated on a transparent indium tin oxide (ITO) substrate. The morphology and crystal structure of the electrodeposited tungsten oxide thin films are investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). X-ray photoelectron spectroscopy is employed to verify the chemical composition and the oxidation state of the films. Compared to the compact tungsten oxides, the porous films show superior electrochemical activities with higher reversibility during electrochemical reactions. Furthermore, they exhibit very high color contrast (97.0%) and switching speed (3.1 and 3.2 s). The outstanding electrochromic performances of the porous tungsten oxide thin films are mainly attributed to the porous structure, which facilitates ion intercalation/deintercalation during electrochemical reactions.

There are five contexts of division algorithm of fractions such as measurement division, determination of a unit rate, reduction of the quantities in the same measure, division as the inverse of multiplication and analogy with multiplication algorithm of fractions. The division algorithm, however, should be taught by 'dividing by using reciprocals' via 'measurement division' because dividing a fraction by a fraction results in 'multiplying the dividend by the reciprocal of the divisor'. If a fraction is divided by a large fraction, then we can teach the division algorithm of fractions by analogy with 'dividing by using reciprocals'. To achieve the teaching-learning methods above in elementary school, it is essential for children to use the maniplatives. As Piaget has suggested, Cuisenaire color rods is the most efficient maniplative for teaching fractions. The instruction, therefore, of division algorithm of fractions should be focused on 'dividing by using reciprocals' via 'measurement division' using Cuisenaire color rods through analogy if necessary.

This study aims to compare the properties of natural dye stuffs, such as color, dyeability, fastness, and marketability, to analyze the differences noted by expert groups regarding the properties of the stuffs, and to make a positioning of the stuffs. A survey of experts in academia, business, and the art of natural dyeing was conducted, with an evaluation of 23 types of the stuff's properties. There is a correlation between the properties of the stuffs, and evaluating dye stuffs differs according to the group to which it belongs. X-axis relates to color and Y-axis refers to fastness in the positioning of the stuff. There are different relationships between properties according to their group. Color is significantly associated with marketability in art experts however, fastness is closely connected with marketability in business. The stuffs can be divided into five clusters. Cluster I includes indigo and persimmon, and is marked by excellent color, dyeability, fastness, and marketability, Cluster II contains safflower and sappan wood, which are excellent colors, yet suffer from low marketability on account of their medium to low fastness. Cluster III includes red, purple, and brown dyes, and onion and rhubarb, and has medium properties. Cluster IV is mugwort and yellow dyes, except onion and rhubarb, and features low properties. Cluster V is loess, featuring medium color and low fastness.

Color-fleshed potatoes 'Hong-young' and 'Ja-young' were developed by RDA, and it has reported that they have high content of anthocyanin. Additionally they show higher radical scavenging activity compared to white or yellow fleshed potatoes. So it will be expected that the consumption of color-fleshed potatoes gradually increase by pre-peeled potatoes and color potato chips. This study was conducted to enhance the utilization of the tuber of color-fleshed potatoes. At first, we isolated four compounds from the organic solvents soluble layer in ethanol extract of tuber, and their structures were characterized by spectroscopic methods and by comparing their data to those in the literature. Their structures were characterized to be caffeic acid (1), chlorogenic acid (2), gallic acid (3) and protocatechuic acid (4) for the first time reported from this source. These compounds were already reported ingredients but considered to exhibit a high physiological activity. The quantitative determination on the four compounds in tuber of color-fleshed [Hong-young (HY) & Ja-young (JY)] and white-fleshed [Superior (SP)] potatoes samples were measured using HPLC. The concentration of caffeic acid in each total fractionations of HY (184.4 g/g) and JY (435.1 g/g) were higher than in total fractionation of SP (31.1). The concentration of gallic acid in each total fractionations of HY (282.1 g/g) and JY (315.2 g/g) were higher than in total fractionation of SP (143.3 g/g). The concentration of chlorogenic acid contents appeared to be highest in total fractionation of SP (954.2 g/g). The concentration of protocatechuic acid in total fractionation of HY (120.3 g/g) was higher than in each total fractionationss of JY (74.4 g/g) and SP (102.7 g/g). Overall, color-fleshed potatoes had higher amount of physicochemical properties than 'Superior'. Therefore, color-fleshed potatoes are expected to be highly valuable items for the development and applications of a functional food. In addition, these results will provide fundamental information for improving sitological value, and breeding of new cultivar.

This study analyzes the experiences of a color therapy program that uses color and fashion directing to influence the psychological characteristics of adolescents, such as emotional intelligence, self-efficacy, and color expression. The subjects of this study were 15 adolescents who participated in B-City Winter School (January 6-15, 2020). Pre- and post-tests for emotional intelligence and self-efficacy were conducted to confirm the effect of the color therapy program that indicated a significant difference at the p<.05 level. Statistical significance was confirmed through the GEE model for formal characteristics used in pre/post and fashion-directed color expression. Peter pre- and post-changes in vocabulary emergence were investigated with a Word Cloud analysis using R program 4.0.2 that extracted the lower and upper categories. The significance of this study is that by expressing both color expression and fashion direction together, a program was provided for adolescents to have richer emotional experiences and career-related experiences. This study examined changes within a short period of time in 15 subjects; consequently, a follow-up in-depth qualitative analysis of the program effect and a post-testing study on maintaining the long-term effect is expected to secure further validity and usefulness of the study results. In addition, new studies are expected to contribute to the development of differentiated fashion-related education programs.
